I have picked up another Scott Bonnar! This time a 450546 which im lead to believe is a lawnking. Only plan to give it a quick tidy up for now, and replace anything that is past its use by date.
When looking for parts, im assuming most exploded diagrams & part numbers for a sb45 17" are relatively the same?
Yes the machine you have is a Model 45 and everything bar the handle bar is pretty much the same as a regular Gull Winged Scotty.
This is a "Dual Aluminium plated chassis" which would date it around 1974, and thus it should have a 2 HP "60102" Briggs engine fitted to it while all the normal Scott Bonnar designated machines still had Kirby 2.5 and 3 HP engines fitted at this point in time. (HK25~H4 and HK30's)
The Lawn Kings were a store brand machine and were priced lower to sell thus they had lower powered engines fitted and cheaper handle bars fitted. This was the only differences between the two variants.

This is correct as the first dual plates were brass units as the original brass units were only a one liner and then a serial number was introduced as a separate line, thus the second plate was introduced as an underscore. Now the only confusion that arose was why they did this in ally and not just get the new ally plate made up as a dual information unit from the start. I strongly feel that a lack of communication around the design in the plates was encountered and thus it only changed after stock of both top and underscore plates was exhausted as the company never ever wasted anything.

Also when I purchased the SB, I noticed it was quite noisy in the engine/clutch housing area. Have since removed the clutch housing and it is still quite "rattely". Obviously these machines are old, but I kind of **expected** the NVH level's to be a little less.
Sadly this much mistreated machine has seen better days. That rear roller is paper thin and not worth repairing. I'd say most of the drive train toothed gears are well and truly worn out as well.
As far as the engine is concerned they never run well with out some sort of weight attached to the PTO shaft. This engine is a much later produced power plant than the mower itself.
Honestly Aiden I'm not sure if this one is worth salvaging because it's going to come at the cost of another machine having to die to give any signs of life to this one. I'd also feel that this chassis will have a few more stress fractures underneath the paint in the engine deck rails than just one, which in that case makes it the heart donor to another.
Sorry to be the bearer of bad news but that's just how it is sometimes unless you have good engineering services at no cost available to you.
As you well know there's good cars and there are bad ones out there and this is the bad one that's been traded in.

Hi Guys, i know some will consider this sacrilege, but i had the tools and time to get this 17" going again. Nothing better than pulling it down and starting from scratch! I am pretty happy with the out come....!
Well you've gone all out on this one and I'm not sure what the sacrilege is apart from it not being restored back to Lawn King specs, actually boo hoo as far as I'm concerned as I've never liked the Lawn King handle bars from day one. Incidentally I've still got a couple of these examples laying around here which I want to move on, so if anyone's interested please write to me.
Now I will say that I've noticed you've managed to pick up another rear roller, replaced the shot reel with an 8 blade unit and replaced the pram bars with Gull Wing units, thus it now looks the part and is an absolute credit to you.
I must ask on behalf of future readers what did you do with the fatigued engine rails ?
Cheers, BB.
